Funny this thread popped up....I have a Progressive Industries EMS-PT50C. I chose the pedestal hook up vs hard wired because I can connect to the pedestal to check power before I get in and setup. Check out their site, loads of info and it has a lifetime warranty...
Now the awesome part of my story...we have been on the road for the holidays. Stopped at a campground and plugged in, the display was calling 255 volts on one keg and 45 on the other...found someone else with one and tried it, showed good power. Mine was shot. Used without a protector at that campground. I emailed them yesterday, first day with Internet, they immediately responded with, call us immediately, we are closing until 5 Jan. I hunted a phone, called and explained everything, I will have one in hand today (they are in NC, I am in CA). I paid for the overnight, otherwise it would have been here Saturday....
They do have 24/7 tech support, call and leave a message, they will get back within the hour...
I purchased mine on Amazon, much cheaper. I am a true believer and their customer service has been fabulous.
